Episode Details

Why do some city streets lose all their trees at once while others stay green? 🌳In Episode 5 of our Urban Forestry series, we dive into the critical importance of species diversity. While uniform rows of identical trees look beautiful, they create a "monoculture" that is highly vulnerable to catastrophic loss.We’ll explore the history of Dutch Elm Disease and the Emerald Ash Borer to see what happens when diversity is ignored. Most importantly, we break down the 10-20-30 Rule—the gold standard for building a forest that can survive pests, disease, and the challenges of climate change.In this video, you will learn:The risks of urban monocultures (Lessons from history).What the 10-20-30 Rule is and how to apply it.How diversity helps cities adapt to climate change.The ecological benefits of a varied canopy for local wildlife.🎓 ISA Exam Insight:Preparing for the ISA Urban Forest Professional exam?
